Abstract: PURPOSE: An apparatus (200) is to provide a multiparty speech connection for use in a wireless communication system(10) which includes movable subrate center(12), control machine(14), public subrate telephone network. CONSTITUTION: The speech signal(210) is encoded by a speech decoder(28) and is transferred to the subrate center through air interface(204). The encoded signal of subrate center is received by the conference circuit(22) as a multiparty conference circuit. A second speech signal transferred to the speech decoder(20) by subrate center passes through conference circuit(22). The conference circuit(22) outputs a single encoded speech signal and transfer through air interface. The transferred speech signal generally is received in movable station, is decoded by speech decoder(208) and then is transferred as a reconstructed speech signal(214). The speech decoder receives the multiplexed encoded speech signal and produces a decoded speech signal.
